public string Text
        {
            get
            {
                string s="";

                for (int i = 0; i < 100; i++)
                {
                    if (i % 10 == 0)
                    {
                        s += i + ",<br />";
                    }
                    else
                    {
                        s += i + ",";
                    }
                   
                }
                return s;
            }
        }

        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                Label1.Text = Text;
              
            }
        }
<asp:DataList id="DataList2" runat="server" DataSourceID="ObjectDataSource2" HorizontalAlign="Left" RepeatColumns="1">
